Noida property search: Am I missing red flags?

Started looking at 2BHKs in Noida. My budget's tight, so Sector 150 is out. Honestly not sure about Amrapali. Heard too many stories about delays and quality issues. Supertech, on the other hand, seems to be delivering projects, but what about hidden charges at possession? My parents keep saying I should check RERA compliance for everyone. Anyone have experience with Supertech's possession process? Are there surprise costs? Is it worth the risk?
